DDP-38003 dihydrochloride, a tranylcypromine (TCPA) derivative, is a novel, potent and orally bioavailable inhibitor of histone lysine-specific demethylase 1A (KDM1A/LSD1). DDP-38003 inhibits KDM1A with an IC50 of 84 nM. DDP-38003 is more active in reducing the colony forming ability and in inducing thedifferentiation of THP-1 cells compared to the 1R, 2S analogue. It exhibited in vivo efficacy after oral administration, determining a 62% increased survival in mouse leukemia model with evidence of KDM1A inhibition. The biological profile of DDP-38003 supports its further investigation as a cancer therapeutic.
| ln Vitro |
KDM1A is inhibited by DDP-38003 at an IC50 of 84 nM. Compared to the 1R, 2S counterpart, DDP-38003 is more effective in inhibiting the capacity of THP-1 cells to form colonies and at promoting their differentiation[1].

| ln Vivo |
Following oral dosing, DDP-38003 has in vivo efficacy as demonstrated by a 62% increase in survival in mouse leukemia models with evidence of KDM1A suppression. DDP-38003 has a half-life of eight hours. Treatment with DDP-38003 significantly increases the survival rate of mice in a dose-dependent manner. At doses of 11.25 and 22.50 mg/kg, respectively, the survival rate rises by 35% and 62%, respectively. One possible oral anticancer drug is DDP-38003[1].

Note: Listed below are some common formulations that may be used to formulate products with low water solubility (e.g. < 1 mg/mL), you may test these formulations using a minute amount of products to avoid loss of samples.
Injection Formulations
Injection Formulation 1: DMSO : Tween 80： Saline = 10 : 5 : 85 (i.e. 100 μL DMSO stock solution → 50 μL Tween 80 → 850 μL Saline)(e.g. IP/IV/IM/SC) *Preparation of saline: Dissolve 0.9 g of sodium chloride in 100 mL ddH ₂ O to obtain a clear solution. Injection Formulation 2: DMSO : PEG300 ：Tween 80 : Saline = 10 : 40 : 5 : 45 (i.e. 100 μL DMSO → 400 μLPEG300 → 50 μL Tween 80 → 450 μL Saline) Injection Formulation 3: DMSO : Corn oil = 10 : 90 (i.e. 100 μL DMSO → 900 μL Corn oil) Example: Take the Injection Formulation 3 (DMSO : Corn oil = 10 : 90) as an example, if 1 mL of 2.5 mg/mL working solution is to be prepared, you can take 100 μL 25 mg/mL DMSO stock solution and add to 900 μL corn oil, mix well to obtain a clear or suspension solution (2.5 mg/mL, ready for use in animals).

Injection Formulation 4: DMSO : 20% SBE-β-CD in saline = 10 : 90 [i.e. 100 μL DMSO → 900 μL (20% SBE-β-CD in saline)] Oral Formulations
Oral Formulation 1: Suspend in 0.5% CMC Na (carboxymethylcellulose sodium) Oral Formulation 2: Suspend in 0.5% Carboxymethyl cellulose Example: Take the Oral Formulation 1 (Suspend in 0.5% CMC Na) as an example, if 100 mL of 2.5 mg/mL working solution is to be prepared, you can first prepare 0.5% CMC Na solution by measuring 0.5 g CMC Na and dissolve it in 100 mL ddH2O to obtain a clear solution; then add 250 mg of the product to 100 mL 0.5% CMC Na solution, to make the suspension solution (2.5 mg/mL, ready for use in animals).

| Preparing Stock Solutions | 1 mg | 5 mg | 10 mg | |
| 1 mM | 2.3619 mL | 11.8097 mL | 23.6194 mL | |
| 5 mM | 0.4724 mL | 2.3619 mL | 4.7239 mL | |
| 10 mM | 0.2362 mL | 1.1810 mL | 2.3619 mL |
*Note: Please select an appropriate solvent for the preparation of stock solution based on your experiment needs. For most products, DMSO can be used for preparing stock solutions (e.g. 5 mM, 10 mM, or 20 mM concentration); some products with high aqueous solubility may be dissolved in water directly. Solubility information is available at the above Solubility Data section. Once the stock solution is prepared, aliquot it to routine usage volumes and store at -20°C or -80°C. Avoid repeated freeze and thaw cycles.
Calculation results
Working concentration： mg/mL；
Method for preparing DMSO stock solution： mg drug pre-dissolved in μL DMSO (stock solution concentration mg/mL). Please contact us first if the concentration exceeds the DMSO solubility of the batch of drug.
Method for preparing in vivo formulation:：Take μL DMSO stock solution, next add μL PEG300, mix and clarify, next addμL Tween 80, mix and clarify, next add μL ddH2O，mix and clarify.
(1) Please be sure that the solution is clear before the addition of next solvent. Dissolution methods like vortex, ultrasound or warming and heat may be used to aid dissolving.
(2) Be sure to add the solvent(s) in order.
